5v to ≈70v dc-dc converter in the 1w range?

AI Thread Summary
A user is seeking a 5V to approximately 70V DC-DC converter in the 1W range for a bio-stimulation device, expressing uncertainty about sourcing components due to limited experience. The discussion highlights the importance of understanding electrical standards like UL544 for safety and compliance, especially for devices intended for human use. There are questions regarding the power source, specifically whether a 5V AC supply is available, and the feasibility of using a DC-DC converter IC for this application. The conversation suggests that creating a prototype requires careful consideration of safety regulations and possibly hiring a licensed professional with biomedical expertise. Overall, the user is advised to gain more knowledge in biomedical engineering and safety standards before proceeding.

I am looking to find a 5v to ≈70v dc-dc converter in the 1w range or the equivalent transformer + diodes. This is for a bio stimulation device and I need a high voltage and low amperage. However, not having spent years researching and buying electrical components, I'm a little uncertain where to look and for what exactly to look for. The requirements are fairly straight forward but turning theory into something that is actually on the market is difficult without having been in the industry for a while. Thanks.

Talk to me about UL544. What is it? Why is it important?
 
This is a biostimulation device to be used how? And for what purpose? on people? Horses? frog legs?

Where is the 5V coming from? You have 5V AC? (you need AC for a transformer)
 
I have a 5v, .2a (1w) pulse system with a 24 Hz/.7 duty cycle that originates from a dc inverter I found that meets those specifications. I know very little about transformers, I mainly know DC. Can you have an AC system that alternates between 0 and 5v instead of -5 and 5v (or whatever)? I would ideally like to just use a DC to DC voltage converter IC that has all the circuity worked out and my guess is that jury rigging something to get the voltage high and the amperage low would mess up the waveform. However, my guess is such a thing does not exist or is really expensive because it is so niche. This is just a proof of principle prototype of an electrical muscle stimulator for use on the human leg; I have a long way to go to be able to have something that will pass any kind of UL/FDA approval but I am aware if the safety concerns.
 
Please study up on Biomedical Engineering (preferably take a few local classes) before trying to do something like this. We won't be able to help you here.

EDIT -- you could also consider hiring a licensed professional EE with Biomedical experience.
 

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
